關於cambridge gce的

你地好
我有幾樣關於GCE既野想請教下
希望你地幫幫我

我係2013年9月想去加拿大讀大學
但係我今年既DSE無報名
而等下次考DSE已經係下年4月既事
因為加拿大既大學通常係3月截止 9月開學
所以我決定考cambridge既GCE
因為佢有一個可以係10月-11月考之後2月放榜

我想請教下IGCSE同GCE O-LEVEL係咪同一個程度?
係咪即係考左IGCSE就唔使考O-LEVEL?

以下係我想入加拿大既個間大學對GCE既收生條件

Applicants must present the following:
GCE A Levels – At least two A Levels in
different subject areas with predicted and
final grades of ‘B’ or higher in one subject
and ‘C’ or higher in another subject.
GCE AS Levels – Two AS Levels are
acceptable in place of an A Level.
GCSE O Levels – At least three different
subject areas at the GCSE O Level with
final grades of at least ‘B’ or higher in one
subject and 'C' or higher in two other
subjects.

如果佢咁寫既話 其實個意思係可以淨係睇A-LEVEL既成績定係連O LEVEL/IGCSE既成績都要睇埋?

如果真係要睇哂兩個成績 我會盡量係今年11月考哂兩個試
因為香港只有得考IGCSE無O-LEVEL
如果我同一個時期考GCE A LEVEL同IGCSE既話
呢兩個考試會唔會撞期架?

希望你盡量解答下我
唔該哂
